  • the pivot lever is lockable in a recess held on the door leaf, so that the opening of the cabinet, the closure of the pivot lever in the recess must be released, after which the pivot lever can be rotated so that the rotation of the pivot lever on the arranged in the associated lock case Pinion is converted into a longitudinal displacement of the locking rod from its locking position into the open position or vice versa.
  • the disadvantage of the known rod lock is that the only safeguard against unauthorized opening of the cabinet in the lock is provided for fixing the pivoting lever in the trough; If the swivel lever is pulled out of the recess by force, opening the door is easily possible by swiveling the swivel lever.
  • the problem that arises in control cabinets in which current-carrying switchgear or other dangerous "electrical systems are arranged is that the live electrical systems are accessible even after an authorized opening of the door, so that inattentive handling poses a risk to the operators concerned. To avoid such a hazard, it is known through use to make the live components in a control cabinet inaccessible by means of an additional cover installed in the cabinet.
  • the invention is therefore based on the object of developing a rod lock of the type mentioned in such a way that there is no danger to operators from live parts and, in addition, the protection against unauthorized opening of the cabinet is improved.
  • the invention provides in its basic concept that the closure holder additionally has a tumbler movable between a release division and a blocking position for fixing the locking rod in its locking position and that for blocking the tumbler in its blocking position which defines the locking rod, a by applying electrical Current-controllable blocking element is provided, the control of which is carried out by a signal source arranged on and / or off outside the cabinet.
  • the invention is associated with the advantage that, despite authorized handling of the actuating device, opening of the cabinet is ruled out as long as the electrical installations are live, because the additional tumbler, which is coupled in its function to the external signal source, moves the locking rod even when authorized Operation in their open position prevented.
  • the blocking member that fixes the movable tumbler in its blocking position is designed as an electromagnet that can be energized, since in this way there is a simple possibility, for example, of supplying the electromagnet with the activation of a suitable controller WO 97/40248 Pf »/ D ⁇ F l ⁇ Wf 4Vrw
  • the tumbler is biased by a spring into its release position releasing the locking rod and held in its blocking position by overcoming the spring force by the energized electromagnet, the current flow to the electromagnet being switched off when the signal source is switched off, the Tumbler can be formed by a linearly displaceable and engaging in the blocking position in a bore of the locking bar bolt;
  • the electromagnet is under current in normal operation and thereby holds against the force of the spring acting on the locking in its release position for the locking rod in the blocking position, in which the locking rod cannot be moved into its open position via the actuating device; If the signal source is actuated accordingly, the electromagnet is de-energized at the same time, and the spring can now press the tumbler into its release position for the locking rod, in which an opening of the cabinet is possible via the actuating device.
  • the tumbler is held in its blocking position defining the locking rod by the energized electromagnet, with switched off signal source, the energization of the electromagnet is set up.
  • a separate circuit that is only set up to supply the electromagnet must be set up, since when the signal source is switched off and the voltage supply is thus switched off, the electromagnet must be energized to control the guard locking.
  • the tumbler is in the form of a pinion which is arranged in a housing which accommodates the locking rod and engages with associated teeth in the associated openings of the locking rod and prevents the rotational movement of the pinion when the electromagnet acting on the pinion is energized is.
  • the signal source is a switch which can be switched on and off and is assigned to the electrical systems located in the control cabinet.
  • the invention provides in a further embodiment that the control of the movable tumbler is one of the Has locking rod actuated contact in its locking position, so that the main switch can only be switched on when the locking rod is in the locking position.
  • This safety measure is advantageous if several control cabinets are connected to a single main switch, so that this main switch can only be switched on when all cabinet doors of all the control cabinets attached to it are securely closed.
  • the invention also opens up the possibility of providing all cabinets, in which systems which are dangerous or inaccessible to unauthorized persons, are provided with additional security against unauthorized opening, such as control cabinets with hydraulic or pneumatic controls, distribution cabinets for telecommunications systems or similar.
  • the control for activating or deactivating the blocking element can also be controlled by a signal coming from outside the cabinet, for example via radio or another data connection to the controller, so that the additional signal only arises on the basis of such a special signal Guard locking allows the opening or closing of the rod lock.
  • the external signal source can be designed as a transmitter / receiver unit, which is assigned a transmitter / receiver unit which is arranged in the interior of the cabinet and controls the blocking element or its power supply.
  • the lock holder and additional electromagnetic guard locking are combined in one component accommodated in the canting space;
